Site description This site, situated in the interior of western Tanzania, is a vast wetland system of limited access, even in the dry season. During times of peak flood the flood-plains of the Malagarasi, Moyowosi, Nikonga, Kigosi and Gombe rivers cover nearly 1,000,000 ha and the permanent swamps along the margins of the rivers and lakes extend over 350,000 ha. The riverine vegetation is dominated by Borassus and Phoenix palms with stands of Acacia woodland along the margins of the flood-plain. The higher ground between the rivers is cloaked in Brachystegia–Julbernardia woodland with patches of groundwater forest in areas with a high water-table. The Moyowosi and Malagarasi rivers both rise in the highlands of Burundi, while the Nikonga, Kigosi and Gombe rivers drain the central plateau south and south-east of Lake Victoria. These rivers join to the east of Uvinza and drain into Lake Tanganyika, 40 km south of Kigoma. The central railway between Tabora and Kigoma crosses the southern edge of the wetland, separating it (except during wet years when the whole area is inundated) from the Ugalla river wetland system (TZ019).
